Hey guys,
I've been lurking here for the last few days, as we hopefully are going to be buying a MO tonight (assuming the dealer is willing to play ball....). Its going to be my wifes vehicle, but like most things we have, i probably won't be able to leave it alone....
So my first (of many in the coming months) question is surrounding the transmission. Let me give you a little background on me, and where i am coming from so my question makes more sense.
I am an avid snowmobiler. Snowmobiles, as you are probably aware, have a different type of CVT, but a CVT none the less. As sledders, we call the CVT the clutches (drive clutch and driven clutch) and the act of modifying said clutch is called 'clutching'. So a lot of times you can REALLY wake a sled up by changing the weights, springs and helix in both clutches to effect the launch rpm, max rpm, backshifting, etc.
That being said, though its a different setup, the principal should still mostly the same on the MO. So my question is, are there any kind of mods that you can do to these transmissions that would give different performance, at different points?
Really, the CVT's in these vehicles have a LOT of complexity that is deffinatly not present in snowmobiles, so it would probably not be a very good idea to do anything, but still...you know how curiosity is. :)
thanks for any input!

Same principle but a very different execution. The MO's pulleys are controlled by a stepper motor and hydraulics - no weights, springs, or do-dads like those found on snowmobiles.
There are no user-serviceable parts on the MO's CVT. In fact, there are not that many Nissan-serviceable parts on the MO's CVT. Nissan doesn't even rebuild the failed trannies. They are sent back to JATCO, the CVT's manufacturer.
It looks like you'll have to limit your clutching to your snowmobiles. I am sure your wife will be pleased to hear that. :4:

I can see a custom designed module that would intercet the signals from the current system an change the timing of things or the hydraulic pressures etc. It will take a very lot of reading and learning about what the current Jacko (sp_ unit does etc.
The big question could you really make it any better than it currently is. Answer that question first, What would you want it to do.
REMBEMBE it is the weak link between the power and the pavement. :D |

| From what I know, it *is* possible to have a sportier and more responsive CVT, but it is not available for the Murano. The caveat? Its the CVT programming in the current model year Altima and Maxima, which have a "sport tuned programming" that is supposedly an improvement over the MO's soft programming. At least thats what the various reviews of the new Altima and Maxima claim - take Edmunds.com - whereas they HATED the Murano's CVT, they rave about the 2007 Alty's CVT, which they say is the best CVT out there and will not make you miss a normal automatic. So it does seem that the CVT can be tuned to feel more powerful and responsive, but you'd have to figure out what they did to the Altima first. |

hum...yeah, i prolly just leave it alone. :D Thanks for the info though!!
Turns out we didn't get the one we were hoping for last night. We got the carfax report on it finally. The dealer had been selling it as a one owner trade in, and according to car fax its had 6 owners, 4 of which were rental agencies, had been in an accident, and had been reposessed, and the dealer purchased it from auction. And even with that information, the dealer refused to go below $20,000 (04 SL w\ 52,000 miles and in fairly decent shape...some rock chips and scratches) for the vehicle, even though we caught them in two lies(also tried telling us that it had 4 options that it deffinately did not have)....so we walked out. A bit frustrating....maybe we are just being unrealistic on price...i dunno...
But the wifey is sold on Murano's for sure, so we'll get one some how!!
Say Eric, are there any on the lots in the cham-bana area? :D
Thanks again for the info! |

Used car dealers... some of the most deceitful people on the planet.

Oh, come on. They're not ALL that bad. I'm sure there's at least ONE used car dealer out there that is respectable.
Mind you, I haven't met one, but I'm sure one exists SOMEWHERE! :D |

| Unless it is a new car, I never buy any of my cars from dealers. Except for a few, the rest are out there to get you....:4: |

About ten years ago I worked as a bartender on weekends. Across the street from the bar was a new and used car dealership. Every Saturday the salesmen would come over and swap stories about how they just screwed someone on a deal. It was like a game to them. Some of the scams they pulled were borderline illegal, but it didn't matter to them as long as they made their numbers. I would laugh while in their presence but as soon as they left I often wanted to just drop a dime on them. Pond scum.
